IMPROVEMENT IN PORTABLE ELEVATORS.

Specification forming part of Letters Patent No. 1 {75,002, dated March21, 1876; application filed August 17, 1875.

Toall whom it may concern:

Be it known that I, VICTOR ANDRY, of the city of New Orleans, in theparish of Orleans and State of Louisiana, have invented a certain newand useful Improvement in Portable Elevators, for use on steamboats,&c.; and I do hereby declare the following to be a full, clear, andexact description of the same, reference being had to the followingspecification, with the annexed drawing, in which- Figure 1 is a sideelevation of my apparatus as erected on the main deck of a steamboat.Fig. 2 is an end view of the same. Fig. 3 is a detached view of thecarriage or elevator-plat. form.

Corresponding parts in all the figures are designated by like letters.

The invention relates to a certain improvement in portable elevators,adaptable to steam boats or barges plying on western rivers, the objectof which is to provide a simple and efficient contrivance by meansof-which steamboats running in a low stage of water shall be enabled toload or unload rolling or other.

freight at the wharf or landings with dispatch and economy. By the useof this simple mechanisml am enabled to accomplish this object with mydevice in half the time required by others with more cnmbrous devices.

In order to enable others skilled in the arts to make and use myinvention, I will, proceed to describe it. x

In the annexed drawing, A main deck of a steamboat, on wh'i eiits thethe apparatus is erected, and secured by suitable bolts? or pins. -.B isthe outer frame of the elevator, which I make of wood, and abouteighteen feet high by six or eight feet Wide, and made with the innerframe B in section, so that when not required it can be taken to piecesreadily and stowed away. 0 represents the carriage or platform. Thisplatform is constructed-with slides, which work in the grooves made inthe vertical standards D. O is a tilting plank, pivoted at c, and fittedwith lugs c and a weight, 0', so as to'keep it in a horizontal position.D is a rope or guy, by means of which the working of the tilting plankisadjusted so as to push the, freight 011' of the platform onto thestage-plank. E is the stage-plank, fitted with the sides or guides E. Frepresents the Wharf or landing, on which the plank E is resting whenunloading freight, and on which the freight is finally landed andreceived, or from which it is taken on board. G is the hoisting-rope,running upon the pulleys or sheaves g g. H is a snatch-block, upon whichthe rope G passes, and is guided on the steam-capstan H and wound two orthree times, so as to obtain a good hold. J are guys, which may befastened to any part of the boat, so as to maintain the frame in itsposition. J are lock-bolts, fitted with keys, the object of which is tofasten the frames B and B together, and to take them apart upon theirremoval. K is an inclined plane, and K are metallic side pieces, boltedto the frame B, and fitted with holes, through which passes the pin 0.The end of the stage-plank bears a metal plate, properly fastened. Thisplate has a notch, 0, cut into it, so as to engage the pin 6 easily, andupon which it rests while unloading freight. The height of the plank canbe adjusted so as to suit the bank or wharf. When the boat is moving,the plank is disengaged from the pin 6 and fastened on the sides offrame B. L is a hogshead or barrel.

To operate my elevator I proceed as follows: The'frame B having beenplaced in position upon the deck A, the guys J are made fast. Theadjustable ropes D are next fastened upon the cleat 01, so as to causethe tilting plank G to oscillate when the platform is' opposite and inline with the end of the plank E. The rope G is then wound upon thecapstan H; and the stage-plank E being placed in its position, and thebarrel or hogshead L being rolled upon the platform, then I start thesteam-capstan, and, by hauling the rope G tight, the platform 0 willrise with the freight until it has assumed the position shown in dottedlines, when the tilting plank 0, being actuated by the guys or ropes D,will shove the barrel onto the platform E, when it will roll ashore bygravity. By slacking the rope G the platform will descend to the deck A,and be ready to receive or discharge rolling freight as fast as it canbe brought from the different parts of the boat.

Having now fully explained the object and purpose of my invention,together with its operation, what I claim as new and useful, and

3. The carriage or hoisting-platform O, as constructed and fitted with atilting plank, C, pivoted at c, lugs c c, and weight 0, in combinationwith steam or other capstan H and snatch-block H, substantially in themanner shown and described, and for the purpose set forth.

VICTOR ANDRY.
